.pdb

Program database files are installed with various programs. They contain data in a structured database format and are typically referenced by the corresponding program while the program is running.

Multiple programs use program database files, but most save the files in a proprietary format. Therefore, a specific PDB file may only be recognized by one program.

PDB files are generated by PDAs that use the Palm OS. The PDB format supports multiple types of data, including text, images, and spreadsheets. It is also commonly used for eBooks distributed on the Palm platform.

Important: The Palm OS has mostly been replaced by other mobile operating systems, such as iOS and Android. It is possible to read PDB files on Android and iOS devices using third-party apps.
